CARTOGRAPHIC MODELLING OF SPATIAL DATA - METHODOLOGICAL ASPECT

摘要

Processing of spatial data in the process of cartographic visualisation requires that the, so - called, measuring scales are applied. Measuring scales are described in publications as such scales which allow for processing descriptive data to the form of a cartographic symbol. And the reference of objects in time, as well as the process of object geometrisation also have similar impacts. Therefore it is proposed to assume two groups of measuring scales applied in cartography: (1) scales referring data to temporal and spatial location of objects; (2) scales referring to features and characteristics of objects. The first group of measuring scales includes: the scale of time, referring data to selected moments and the geometrisation scale, which connects the process of object geometrisation with its visualisation and location on a map. Geometrisation of an object concerns determination - basing on its spatial dimensions and the assumed modelling scale - of the dominating or preferred geometric feature of the object, what significantly influences the way of its locating and cartographic presentation.
